Flame-retardant wall covering material

摘要

The wall covering material has a front cover layer (1) containing flame-retardant substances and polyester fibres and a rear foam layer (2). A perforated aluminium foil (3) is disposed in between. The foam layer (2) contains flame-retardant additives, is elastic and gas-permeable. In addition to good insulation capacity and sound absorption, outstanding flame resistance is obtained.
